  • the present invention relates generally to Wireless Local Area Network (WLAN), especially to a method for implementing presence information interaction of a WLAN subscriber along with a system and a terminal thereof.
  • WLAN Wireless Local Area Network
  • the subscriber's presence information in PRESENCE service is managed by the network, wherein the presence information comprises subscriber's contact way, current status, subscriber's terminal information, service and service element information etc.
  • the subscriber, subscriber's terminal, service and service element information are called presence entity all together.
  • PRESENCE service provides the above information for different watchers according to the predefined rules, and watchers can actively demand for a presence entity's information, or predefine to be notified as soon as the information is changed.
  • the presence information For instance, when a subscriber arrives at his office, he can set the presence information as cellphone shut-off, office telephone available, and Email available. When the watcher needs to contact this subscriber, he can dial the office telephone or send an Email.
  • Presence entity information can be set manually through terminal, or the network provides presence entity information and the terminal just sets the rules and scope of this information. For example, if the watcher needs to talk with the subscriber, he can predefine the status information of this subscriber, and he will be notified once status information of this subscriber changes into power on. For example again, when the subscriber's cellphone is changed from shut-off status to power-on status, a PRSENCE system finds subscriber's setting rules which set that this subscriber's information can be provided for watcher 1, but not for watcher 2. Then the PRSENCE system updates the information for watcher 1, while maintains the original information for watcher 2.
